Abstract
Abstract Apparatus for decreasing stresses and pressure generated to a person's lumbosacral spine while sitting or lying supine, prone, or on the side comprises a belt which fits around the waist, and leg supports which attach to the wearer's legs between the knee and ankle. The belt has a series of foam pads positioned in such a way to help maintain the correct anatomical position of the lumbosacral spine while the person is sitting or lying down, and the leg supports are designed to minimize forces generated in the lumbosacral area from muscular tension. Such stresses and pressures may include; stretching forces on the outer wall of the disc, the annulus fibrosis, stretching forces on the ligaments, stretching forces on the back muscles, and intradiscal pressure.
